Patented June 23, 1931 UNITED STATES PATENT OFFICE ALBERT LINDSAY DOERING, or GERMANTO N, PENNSYLVANIA, ASSIGNOR T .1. s. THORN COMPANY, or PHILADELPHIA COUNTY, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA METALLIC wINDoW sriwcmunn Application filed. December 31,1929. Serial No. 117,627.

My invention is applicable to what are known as double hung windows, including a jamb frame in which two sash frames are mounted to reciprocate parallel with each. other, and relates particularly to means for tween the sash slideways in the jamb frame,-

in cooperative relation with flanges on both sashes. Said sash flanges which cooperate with said weathering strip have respective J-shaped edges and said weathering strip is I also J-shaped at both of its edges and carries inthe bights of those edges respective weathering caps of resilient antifriction metal, each adapted to bear upon opposite sides of the J bights in said sash flanges. As herein-I after described, each of said caps'is preferably formed of a strip of bI'OIlZQWhlCh is evo-' V lutely bent and with its inner edgeengaged in the bight of theJ flangeof the weathering strip and with its outer edge'free for resilient contact with the respective sash flanges; whereby the maximum freedom of movement of said cap is afforded, without permitting accidental displacement thereof. Preferably, each sash style is provided with two J- shaped flanges, andthe flangeswhich are remotefrom said weathering strip have similar respective weathering caps.

Said sash flanges are provided wlth means for detachable connection with chains or other flexible connectors from the sash frames to sash counterbalance weights and, as hereinafter described, the construction and arrangement are such that removal of ascetlon of said weathering strip affords access; g pp s p ll flanges 26 and 27 ex 9 to the connections between the sash frames tendlng into said grooves 13 and 14; Said and the counterbalancing means, which means are concealed when the weathering strips are in their normal position inthejamb frame. However, that construction and arrangement 1 are claimed in my copendin plication Serial No. 417380 filed December 30, 1929 for Letters Patent of the United States.

My invention includes the various novel features of construction and arrangement" hereinafter more definitely specified.

In said drawings; Fig. I is a plan sectional view of; one side of a double hung window structure, conveniently embodying my invention. l 1

* Fig. II is a cross sectionalview of the resilient antifriction metal capping strip, in the form which it assumes when free from the sash flange in which it is shown compressed in Fig. I. A

. Fig. III shows a modified form of Weathering cap affording the minimum amount of frictional contact surface.

Referring I to Fig. I; each of the jamb frames '1 is formed of two pieces of sheet metal 2and ,3 which are preferably detachably connected, as described in my copendng application aforesaid. Said piece 2 has its opposite edges 5 and 6 bent to J-shape and is pressed intermediate of its edges to form the outer finish molding 7 and inner finish molding 8. The other jamb piece 3 has its opposite edges 9 and 10 respectively fitted in said J-flanges 5 and 6, and is bent intermediate of its width to form vertically extending grooves 12, 13, ll,'and and is normally held in rigid relation with thejamb piece 2 in the position shown,'by vertical series of screws 17 which extend between saidgrooves 1'3 and 14 and" are in threaded engagement with respective yoke bars 19 which have inwardly turned ends 20 and 2l respectively overlapping said J flanges 5 and 6, as shown.

Each such jamb is provided with removable weather strip sections 22 which are detachably held in rigid relation with said jamb frame "plate 2 by screws 24. Each of said weatherin strips 22 is channel shaped, havflanges are J-shaped at their inner edges with their short limbs turned toward each other, and carry respective weathering caps 29 and 30 which are precisely alike, but with their free edges 31 and 32 presented in opposite directions.

Each of said strips 29 and is primarily of the cross sectional configuration shown in Fig. II, being preferably formed of a strip of primarily plane antifriction spring metal which has been bent and folded in the evolute form shown, so that its inner edges 34 may be seated in the respective J bight of the weathering strip 22.

Said jamb structure is adapted to cooperate with the outer sash 36 and inner sash 37 which are double hung in vertically slidable relation therewith. Each vertical style of said sash 36 has weathering flanges 38 and 39 having J-shaped edges respectively extending in said jamb grooves 12 and 13, and each vertical style of said sash 37 has weathering flanges 41 and 42 having J-shaped edges respectively extending in said jamb grooves 1 k and 15. Said sash Weathering flanges 39 and 41 embrace in their J bights the weathering caps 29 and 30 of said weathering strips 22, so that said strip is common to a plurality of sashes which it maintains in weathering sealed relation with said amb frame while permitting the sashes to be sealed therein with the minimum amount of friction.

I also find it convenient to provide each of said sash weathering flanges 38 and 42 with respective weathering caps 45 and 46, precisely like said weathering caps 29 and 30 but with their free edges 47 and 48 presented in opposite directions.

The effect of such construction and arrangement of the weathering caps 29 and 30, 45 and 46 is to permit them to automatically adjust themselves in weathering contact with the opposite vertical side walls between which they are compressed, with the minimum amount of frictional resistance to the relative sliding movement of the sash frames 36 and 37 in said jamb frame 1.

I prefer to provide said sash weathering flanges 39 and ll with means, for instance the hook bars 51 and 52, for detachable connection with chains or other flexible connectors 53 and 54 from said sash frames 36 and 37 to sash counterbalance weights 56 and 57 so that removal of a section of said weathering strip 22 affords access to such connections between said sash frames and such connterbalancing means, which means are concealed when the weathering stri s are in their normal position in the jamb rame, as shown.

However, the construction and arrangement of said weathering caps and the flanges with which they are engaged, as above described, are such that they are adapted to cooperate with any jamb structure having suitable grooves therein, regardless of the specific form of the window frame or the sash eounterbalancing means therein.

Moreover, such a weathering strip as indicated at 22, provided with weathering caps 29 and 30, is adapted for sealing joints between a window frame and sashes by resilient contact of the weathering edges 31 and 32 with the surface of the sashes, regardless of the specific construction of the latter.

Moreover, in the form of my invention shown in Fig. III, the weathering cap 59 is angularly bent instead of being curved, with the advantage that it affords a minimum area of frictional contact surface with the jamb at its opposite portions 60 and 61. However, it is not as easily made nor as durable as the curved form of cap above described.

An important advantage of the form of sash styles above described is that it permits glazing with putty, as distinguished from glazing with strips of metal secured by screws, which is the usual practice. In order to glaze with putty, it necessary to have a considerable surface of the style extending transversely to the glass for engagement with the putty. Although such a surface might be afforded by making the styles L-shaped (leaving off the sash flanges 38 and t1) such construction would leave a space between the outer surface of the style and the inner surface of the jamb, which would not only be unsightly, but would admit the weather between the upper sash and the amb. There fore, it is not only advantageous to provide the sashes 36 and 37 with the extra flanges 38 and 4:1 to cover the crevices which otherwise would be left between the styles and the jamb, but to afford a double weathering joint for each sash. Therefore, I desire to broadly claim a window sash with such double weathering means as above described, and particularly such a sash with means upon one of its weathering flanges to engage a sash counterbalance.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined inthe appended claims.
